#3 was a perfect peak. The B.o.B remix did nothing for the single and it peaked at #3. If the single featured someone like Bruno Mars, it would have definitely given it a significant boost.
First of all, TOTGA is one of my fave Katy songs too. But she did all she chould: remixes, acoustic version, discounts, a great music video with a star on it. A #3 peak is great (even more for a 6th single), so I couldn't be more grateful!
If she wanted that record, Peacock would have peaked at #1 and TOTGA maybe should have been the 7th single after that.
